Brunei is a small, sleepy country village. If you are coming from Europe it will be a big shock. Everybody knows your business. Grocery shopping can be very hit and miss as most products are imported and expensive. e.g. 2 litres of fresh milk will set you back about $10usd if there is stock!!!

Petrol is cheap 25p/litre but there is nowhere to drive.
RB has gone through a period of rebranding and trying to reinvent its self.
There has been a flood of expats leave in recent years (some by choice, some not) due to downsizing and consolidation. The pilot contract conditions have steadily been eroded, Annual Leave Ticket up until recently was confirmed business class, now it's economy class. 2012 saw an increase in the daily travel allowance, the first rise in 10 years!!
